英文摘要	Transition metal oxynitrides have now, garnered growing interest in our quest for highly efficient alternatives to Pt in direct methanol alkaline fuel cells. Herein, carbon supported Co3Mo2OxN6-x was synthesized via a simple two-step approach wherein the reactants undergo refluxing and heat treatment in NH3. For the as-prepared Co3Mo2OxN6-x , catalyst, uniformly dispersed on XC-72, with the particle size averaged at 5 nm, the catalytic activities toward oxygen reduction reaction in alkaline media are related to the commercial Pt/C, such as the comparable onset potential (0.9 V vs RHE), half-wave potential (0.8 V vs RHE), and even higher specific activity (82.7 mA cm(-2) at 0.7 V). Significantly, the Co3Mo2OxN6-x catalyst was highly stable in terms of 95% current retention after 12 h chronoamperometry measurement, indicative of favorable prospect for the non-noble cathodic catalyst in alkaline fuel cell.; National Natural Science Foundation of China [11179001]; National High Technology Research and Development Program [2012AA052201, 2012AA110102]; SCI(E); PubMed; ARTICLE; dgxia@pku.edu.cn; 43; 29536-29542; 8
